They aren’t the tariffs other countries are imposing, they are basically the trade deficit ratio instead. A country could have a 0% tariff on American goods but if Americans had a trade deficit with that country they would have been slapped with a tariff.
Fakest of fake news; no developed country (except a few weird microstates) has effective tariffs higher than about 3%. Bizarrely, he based it on _trade deficits_. Today, only two countries have effective tariffs rates >20% (Bermuda and the Cayman Islands), though it will be three next week.
(Based on the World Bank metric; WTO uses a slightly different metric and says there are three; Bahamas, Sudan and Iran.)
